A lens mount is a mechanical interface that connects a camera body to a camera lens. Different camera manufacturers, such as Canon, Nikon, and Sony, use specific lens mounts, which means that lenses designed for one brand typically cannot be used on another without an adapter. The design of the lens mount affects the alignment and communication between the lens and the camera, influencing factors like autofocus and image stabilization. Lens mounts come in various types, including bayonet and screw mounts. The choice of lens mount can impact a photographer's options for lenses, as each mount has a unique set of compatible lenses. Understanding lens mounts is essential for photographers when selecting equipment to ensure compatibility and optimal performance.
